I am preordering the next ME (unless some wildly horrible fact comes out about it) but not because of any PR excitement, but because I have enjoyed every Bioware single-player game to date, especially ME2 and ME3.

There are many news bits on this site and even on regular news sites like cnn which make me wonder who on earth cares about such "news" but I would rather a site err on the side of more information rather than skip too many news bits. That said, I would not become enthusiastic just because a game is in a playable state at the moment. I'm much more interested in release dates.

If they are making a prequel, it would be hard for me to buy this game - for the same reason it is hard (for me) to replay nowaday series and enjoy its story. IMHO it would be also an evidence that they screwed the lore so much, that they don't know what to do next with their wretched conlusion of the original saga.
But if reviews were superb I would give it a try with curiosity… Ofc after ME3 I will wait long enough to read/watch reviews other than ign's or gamespot's hype. I don't want to rewrite some conspiracy theories about developers paying them for reviews, in fact I want to say sth worse: I think that their love to all sorts of cliches, acceptance for intellectual marasmus, ingorance for the narrative bullshit and plotholes which are so devastating for RPGs …ufff… is one of the reasons developers are not pushing the level of storytelling, plot, ideas of their games higher and higher - instead: lowering it. It is a small exaggeration but i think there is a truth in it.

I wouldn't object if the sex-scenes were a bit more erotic like an intense romantic Hollywood movie. Emphasis not on naked body-parts, but on funny situations, not entirely serious encounters, lots of playful creative dialogue, sometimes with erotic overtones. Arcs leading to lascivious scenes without showing much skin, but a lot more emotions instead and professionally designed sexy clothes hiding more than they are showing.

Witty characters, really good looking girls ==> who can appear in new costumes and uplifting romance with wild turns, sort of a very enjoyable soap-opera in space that makes us fall in love with the characters.

Doesn't need to take itself too seriously. The best Asari girl I saw in a Citadel shop for example, awesome sexy model with an angelic voice and compared to her Liara was ridiculously unattractive (voice and looks).
